BOM rule hits · not reviewed — A hit means a BOM line matched this category's rules (ruleset 1.0.1+12960cbec977). It is a lead to read, not a located or reviewed circuit; several lines in one category are not several circuits.
Selection parameter template (suggestion)
What one usually states when choosing a circuit of this kind — not the parameters of any design or module listed here, and never a filter.
| Parameter | Suggested range or common values | Where it comes from |
|---|---|---|
| Operating voltage (V)Decisive | 3.3 to 48 V | Inherited from Protection |
| ESD / surge ratingDecisive | Free text | Inherited from Protection |
| Clamping voltage (V)Important | 5 to 80 V | Inherited from Protection |
| Junction capacitance (pF)Important | 0.2 to 500 pF | Inherited from Protection |
| ChannelsFor reference | 1 to 8 | Inherited from Protection |
